specific Embodiment approach 1
[0014] Specific implementation mode one: combine Figure 1 to Figure 3 To illustrate this embodiment, a precast concrete slab-column node described in this embodiment includes a precast concrete column 1, a precast concrete slab 2, four lower support angle steels 4 and four upper end fixed angle steels 5, and the middle part of the precast concrete slab 2 is provided with Rectangular through hole 2-1, prefabricated concrete column 1 is vertically inserted in rectangular through hole 2-1, and the four side walls of precast concrete column 1 are provided with a lower end support angle steel 4 and an upper end fixed angle steel 5, each One end of the lower support angle steel 4 and the upper end fixed angle steel 5 is fixed on the side wall of the precast concrete column 1, the other end of each lower support angle steel 4 is fixed on the lower end surface of the precast concrete slab 2, and each upper end fixed angle steel 5 The other end is fixedly connected to the upper end su...
specific Embodiment approach 2
[0016] Specific implementation mode two: combination Figure 1 to Figure 3 To illustrate this embodiment, a precast concrete slab-column joint described in this embodiment also includes a plurality of column-through bolts 7 and a plurality of plate-through bolts 8, and the two opposite lower end support angle steels 4 are fixed between the two opposite upper ends. The angle steels 5 are respectively connected by a plurality of through-bolts 7 , and the lower support angle steel 4 and the upper end fixed angle steel 5 on each side are respectively connected by a plurality of through-plate bolts 8 . The undisclosed technical features in this embodiment are the same as those in the first embodiment.
[0017] In such a design, one end of the lower supporting angle steel 4 and the upper fixed angle steel 5 is fixed on the precast concrete column 1 through a plurality of column-through bolts 7 , and the other end of the lower supporting angle steel 4 and the upper fixed angle steel ...
specific Embodiment approach 3
[0018] Specific implementation mode three: combination Figure 1 to Figure 3 To illustrate this embodiment, four embedded steel plates 3 are arranged on the upper and lower end faces of the precast concrete slab 2 described in this embodiment. The embedded steel plates 3 are arranged on the edge of the rectangular through hole 2-1, and the lower end supports the other end of the angle steel 4 It is affixed to the embedded steel plate 3 on the lower end surface of the precast concrete slab 2 , and the other end of each fixed angle steel 5 at the upper end is affixed to the embedded steel plate 3 on the upper end surface of the precast concrete slab 2 . The undisclosed technical features in this embodiment are the same as those in the first or second specific embodiment.
[0019] In this design, the embedded steel plates 3 are arranged at the upper and lower ends of the precast concrete slab 2, so that the fixed angle steel 5 at the upper end and the supporting angle steel 4 at ...
